Apple released an update to enhance the security of bugs prevailing in its Mac OS X Yosemite’s Network Time Protocol Facility. After this update, it has reached its target to fix numerous amounts of bugs and issues present in its latest operating system.

The company released the software update so that it may curtail several complaints lodged against the Unix-based systems including Apple’s own OS X’s security vulnerabilities. The main issue pointed out was the Network Time Protocol NTP, which synchronizes the system clocks.

These bugs were first flagged in security bulletins from the US Department of Homeland Security and the software engineering institute of Carnegie Melon University late last week.

Apple released these updates through its own dedicated software update system that previously released security patches which only needs user approval. This software update system was specifically developed by Apple for this very purpose two years ago but hadn’t been used by the company for quite some time.

An Apple spokesperson said that the update is quite seamless and the system doesn’t even need a restart after it.
